| 摘 要： | 河北省兴隆县陡子峪铁矿是近年新发现的一个鞍山式铁矿,区内太古界迁西群上亚群跑马场组(Arp)地层中发现磁铁主矿体5条,次要矿体及矿化体众多。磁铁矿体规模较小且分布零散,但数量较多。通过对本区控矿因素进行分析,认为赋矿围岩岩性多为由基性火山岩变质而成的角闪斜长片麻岩(局部麻粒岩),原岩中沉积岩的发育程度较低,而鞍山式铁矿与原岩中沉积岩的发育程度正相关,从而导致形成的磁铁矿规模小、厚度薄、层数多、矿体零散。

| Abstract: | Douziyu Fe deposit in Xinglong of Hebei is an Anshan-type iron deposit which is discovered in re-cent years.In this area,5 main magnetite orebodies and other many minor ores body and mineralized bodies are found in Paomachang Formation of upper sub-group of Qianxi Group of Archean Erathem.The discov-ered magnetite orebodies are small-scaled and scattered,but are numerous in amount.Through the analysis of ore-controlling factors in the area,it is believed that the host wall rock is mainly the amphibole plagiog-neiss （partly granulite）converted from basic volcanic rock,and sedimentary rock in protolith is poorly devel-oped.Because the development level of Anshan type iron ore is positively related to that of sedimentary rock in protolith,the magnetite is small-scaled,thin,multi-layered and scattered. |
